TRAP FOR SINKS, BATH-TUBS, AND THE LIKE.

Specification of Letters Patent.

Application filed May 26, 1905. Serial No- 262,364.

rateiited March 6, 1906.

1'0 (2M whom it may concern:

Be it known that I, ARTHUR SAVARD, a British subject, and a resident ofOmaha, in the county of Douglas and State of Nebraska, have invented anew and Improved Trap for- Sinks, Bath-Tubs, and the Like, of which thefollowing is a full, clear, and exact description.

This invention relates to traps; and it consists, substantially, in thedetails of construction and combinations of parts hereinafter moreparticularly described, and pointed out out in the claims.

The invention has reference more especially to traps for sinks,bath-tubs, washbasins, and the like, pertaining generally to the type ofsuch devices forming the subject of Letters Patent N 0. 782,760, grantedtoime on the 14th day of February, 1905, and wherein is described a trapadmirably adapted as an attachment for sinks and the like already inuse. v

One of the principal objects of the present invention is to referred towhich in its practical entirety forms an integral part of the sink,bath-tub, or washbasin with which it may be associated and which issimple in-construction and comparatively inexpensive to manufacture,besides being of easy access for the purposes of cleansing or empt g thesame of its accumulated contents and possessing the capacity for longand repeated service.

A further object of the .invention is to dis pense with several of theelements necessarily employed in the structure of my former LettersPatent referred to and to overcome numerous disadvantages quentlyencountered in the use of many other structures hitherto devised withlike ends in view.

The above and additional objects are attained by means illustrated inthe accompanying drawings, forming a part of this specification, inwhichsimilar characters of reference indicate corresponding parts in theseveral views.

' Figure 1 is a vertical sectional view on the line 1 1 of Fig. 2 of aportion of a sink, bathtub, washbasin, or the like having my improvedtrap embodied in connection therewi th. Fig. 2 is a top plan viewthereof, and Fig. 3 is a View in detail of a portion of the structurelooking at Fig. 1 from the right.

Before proceeding with a more detailed description it may be stated thatin the form of provide a trap of the character and objections fre'substantially such as are 1 my improvements herein shown I employ aspecially-constructed receptacle cast integrally with the sink orsimilar structure with which the same is associated, special means beingemployed adjacent the outlet-opening of the receptacle for preventingsiphoning of the water therein, which forms the seal at the lower partthereof. I also employ a special inner receptacle of suitableforaminated or reticulated material, the same being self-supporting inthe receptacle first named, so as to be capable of being readily liftedout or removed wliencver desired. Other special features of constructionare employed, and while I have herein shown my improvements in a certainpreferred embodiment it will be understood, of course, that I am notlimited thereto in precise detail, since immaterial changes therein maybe resorted to coming within the scope of my invention.

Reference being had to the drawings by the designating charactersthereon, 1 represents what'may be termed the outer receptacle or casingof my formed integrally tub, or washbasin 3, withwllich it is intend edthe trap shall be associated in use, the joinder between the two beingeffected by means of an annular recessed and outturned flange member 4.(See Fi 1.) Said outer receptacle is of any desired eight and diameter,and formed in the side thereof at a suitable part of its height is anoutlet-opening 5, surrounding the edge of which is anexternally-threaded tubular branch 6, to which may be fitted the usualoutlet or exit pipe. (Not shown.) The lower part of the outer receptacle1 is of reduced diameter, as shown, thus to form a downward hollowextension 7, which is closed at its lower end by means of a screw-plug8, fitting within the same and preferably formed in the upper surfacethere of with a recess 9, opening to the interior of the said outerreceptacle 1, said extension being formed for the full width of theouter receptacle, as shown.

Leading at from the upper edge of the outlet-opening 5 in the outerreceptacle 1 is an apron or arched member 11, the lower extremity 12 ofwhich extends below the plane of the upper surface of the b0ttom 13 ofthe said receptacle and enters for a suitable extent the interior of thesaid downward extene sion 7 thereof. By means of this embodimentsiphoning of the Water or other liquid 14, forming a seal for the'trap,is prevented improved trap,

at 2 with the sink, bath- ITO - facilitate insertion and removalthereof, the

upper end of this receptacle being closed by means of a lid 18, hingedat 19, as shown. The entire structure of the said inner receptacle 16 ispreferably of foraminated material, because of the fact that it isstronger and better suited in many res ects than when made ofreticulated materia althou h it will be understood that the lattermateria may be employed therefor in some instances. The bottom of theinner receptacle is referably concaved and intersects with the sidesthereof in such manner as to avoid angles and corners, which would beapt to become bent or indented by contact with external objects in thehandling of said inner receptacle.

It is thought that the construction and advantages of my improvedstructure will be fully understood without further detailed descri tionthereof.

avingthus described my invention, I

claim as new and desire to secure by Letters Patent 1. A trap comprisingan outer rece tacle forming an integral part of a sink, bat -ti1b or thelike and contracted at its lower extrem- 'ity to form a hollowextension, the latter being for the full width of the receptacle andclosed by a screw-plug, an arched member I extending from the upper edgeof the outletopening ofs' said receptacle and having the lower extremitythereof extending below the plane of the bottom of the receptacle and 4within the said hollow extension, and an inner receptacle ofjoraminatedmaterial removably fitted within said outer receptacle at the upper partthereof.

2. A trap comprising an outer rece tacle forming an integral part of asink, bat -tub or the like and contracted at its lower extremity to forma hollow extension, the latter being for the full width of thereceptacle and closed by a screw-plug, an arched member extending fromthe upper edge of the outletopening of said receptacle and having the alower extremitythereof extending below the plane of the bottom of thereceptacle and within-the said hollow extension, and an inner receptacleof foraminated material removably fitted Within said outer receptacle atthe upper part thereof, said inner recepta ole being self-seating withinthe said outer receptacle with the sides thereof ta ering downwardly andthe bottom thereo concaved.

3. A trap for sinks, bath-tubs or the like 3 comprising an outerreceptacle having an outlet-opening therein at one side and formed atits lower end with a downward extension dis osed for the full widththereof and rovid ed with a closing device, and an arc ed member leadingfrom the up er edge of said outlet-opening and extendin below the planeof the upper surface of the ottom of the receptacle substantiallyintermediate of opposite sides of the said downward extension wherebysiphoning of the liquid forming the seal for the'trap is obviated.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ARTHUR SAVARD.
